Visitors to the Oxwich Bay Hotel were able to spot the filmmakers along with boats on the popular beach.

And there's speculation that it may be related to the upcoming Netflix production of The King.

Netflix confirmed that filming for the production was due to start in the UK on June 1.

The King, which is due to air in 2019, will star Oscar nominee and Call Me by Your Name actor Timothée Chalamet as King Henry V.

He will star alongside Robert Pattinson and Joel Edgerton, who is also a co-writer of the movie.

Inspired by elements of Shakespeare’s Henry IV and Henry V plays, the story follows a young, disgraced prince, Hal (Henry V), who inherits the crown after his brother dies in battle just prior to his coronation.
